The Astrophysical Journal (ApJ) is a peer-reviewed scientific journal of astrophysics and astronomy, established in 1895 by American astronomers George Ellery Hale and James Edward Keeler. The journal discontinued its print edition and became an electronic-only journal in 2015.[2]
Since 1953, The Astrophysical Journal Supplement Series (ApJS) has been published in conjunction with The Astrophysical Journal, with generally longer articles to supplement the material in the journal. It publishes six volumes per year, with two 280-page issues per volume.
The Astrophysical Journal Letters (ApJL), established in 1967 by Subrahmanyan Chandrasekhar as Part 2 of The Astrophysical Journal, is now a separate journal focusing on the rapid publication of high-impact astronomical research.
The three journals were published by the University of Chicago Press for the American Astronomical Society until, in January 2009, publication was transferred to IOP Publishing,[3] following the move of the society's Astronomical Journal in 2008. The reason for the changes were given by the society as the increasing financial demands of the University of Chicago Press.[4] Compared to journals in other scientific disciplines, The Astrophysical Journal has a larger (> 85%) acceptance rate, which, however, is similar to other journals covering astronomy and astrophysics.[5][6]
On January 1, 2022, the AAS Journals, including ApJ, changed to an open access model, with access restrictions and subscription charges removed from previously published papers.[7] Articles accepted after October 11, 2022, will be published under the Creative Commons license CC-BY-SA 4.0. Non-open access articles accepted before that date will be free to access but will still need permission to reuse.
